MACHINE FOR POLISHING OR SMOOTHING MOLDINGS.

T at whom it may concern: 7

Be it known that I, JOHN FLEISOHMANN, a subject of the King of Bavaria,residing at Baltimore, in the State of Maryland, have in- --ventedcertain new and useful Improvements in Machines for Polishing orSmoothing'Moldings, &c.;. and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

' the same; Fig. 3, a view in cross-section of one form of polishing orsmoothing block; Fig. 4, a similar view of another form of polishing orsmoothing block; Fig. 5, a detail view of the block-holder. Similarletters and figures refer to similar parts throughout the several views.

Reference-numerals 1 2.3 4 indicate the pieces forming the sides of theframe, and 5 and 6 the pieces forming the ends thereof. The top iscomposed of two pieces A A, having a longitudinal space a between theirinner edges, in which space is located a longitudinal beam B, thepurpose of which will presently appear. A horizontal power-shaft C,journaled in suitable bearings secured to one end of the frame, isprovided with bandpulleys D and E, the pulley D being con nected by aband F with a pulley G, secured on avertical shaft H, journaled insuitable bearings secured to the opposite end of the frame, and thepulley E connected bya band i I with a pulley K, secured on a verticalshaft L, journaled in suitable bearings secured to cross-pieces 7 and 8,respectively. Secured to the longitudinal beam B is a guideway-frame M,composed of two vertical posts m m and two horizontal guide -pieces m m,between which operates a reciprocating block N, provided with a slottedend n,

Patent No. 423,748, dated March 18, 1890.

which receives one'end of a connecting-link O, the other end beingattached to a crankarm P, secured upon the upper endof the verticalshaft I-I.

.Adjust-ably secured to the reciprocating block N is a polishing orsmoothing block holder R, having one end slotted at r, and

provided with perforations r r as shown in Fig. 5. This holder isattached to the outer side of the reciprocating block by a bindingscrew7 and can be adjusted to any desired height. The polishing orsmoothingblocks S S (shown in Figs. 3 and ,4) are attached to the holder by meansof binding-screws Working through the perforations 0" T and are of aform to correspond with that of the work to be operated upon. Theoperating-surfaces of these blocks are covered with a suitable polishingor smoothing material, which, if it be sand-paper or emery-cloth, isheld by springs a: 00 and by strips or cleats secured in place byscrews.

Located opposite to the guideway M is a curved guidewayT, carrying areciprocating block V, provided with two oppositely-projecting arms o 12Adjustably secured to said block is a holder r, similar to holder R,

carrying blocks W W for polishing or smoothing curved or convex andconcave surfaces, it being understood that the blocks S S are forpolishing or smoothing straight or plane surfaces. A connecting-link 20connects either arm 12' or o with the crank-arm P, said link beingprovided with a series of holes near its outer end, as shown, in orderto lengthen or shorten the stroke. ing concave surfaces the guideway Tis reversed, as shown by dotted lines in Fig. 2, and the connecting-linkw shifted to arm 0 In polishing or smooth-.

- .A vertical shaft Y, journaled in suitable bearings secured to theside pieces of the frame, carries on. its upper end a polishing orsmoothing wheel y, and receives power from the shaft L by means ofa-belt y. I Polishing wheels of different sizes and with various stylesof peripheries may be used on this shaft. Power being applied to theshaft 0 by means of the crank c or a pulley, (not shown,) the polishingor smoothing blocks are reciprocated at either a high or low rate ofspeed, as may be desired. The work to be operated upon is held upagainst the said polishing or smoothing blocks and manipulated by hand.

It is obvious that the reciprocating blocks and Wheel may be operatedall at the same time or singly, as desired.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isl 1. In a machine for polishingstraight and curved surfaces, the combination, with a supporting-frame,of a straight guideway pro- Vided'with a reciprocating block and interchangeable polishing blocks, a reversible curved guideway provided witha reciprocating block and suitable polishing-blocks,

the shaft H and its crank-arms, the connect ing-links for connecting thereciprocating blocks to the crank-arms, and mechanism, substantially asdescribed, for operating the said blocks either singly orsimultaneously, as specified. v

2. In a machine for polishing straight and curved surfaces, thecombination, Witha sup porting-table, of astraight and curved guidewaymounted thereon, each of said guideways provided with a reciprocatingblock and interchangeable polishing blocks, the shaft H and itscrank-arms, the connectinglinks for connecting the reciprocating blocksto the crank-arms, one of said links being provided with holes, wherebythestroke may be shortened or lengthened, and mechanism,

substantially as described, foroperating said blocks either singly orsimultaneously, as specified.

3. In a machine for polishing straight-and curved surfaces, thecombination, with a supporting-table, of a straight and curved guide-Way mounted thereon, each of said guide- Ways provided with areciprocating block carryinginterchangeable and'adj ustablepolishing-blocks, and connecting-links for con necting the reciprocatingblocks with mechanism, substantially as described, for operating saidblocks either singly or simultaneously, as specified.

4., The combination, with the supportingframe havinga straight guideway,and with a curved guidevvay'mounted' thereon, said guideways beingprovided with polishingblocks,'of connecting-links O and W, connectingsaid blocks with mechanism, substantially as described, for operatingsaid blocks either singly or simultaneously, as specified. In testimonywhereof I affix my signature in presence of two witnesses.
